people who wanna strap a random supercharger onto their engine just because they got that one cheap and dont have a clue what's involved.

Nils, you're digging a hole quick man.

I believe i would be the one you are referencing here, and yes, i had planned to. Again i say, you could swap pulleys, or put on your big boy pants and set up some supporting mods to run boost which another company thinks is good for a 3.0 liter engine.

Either way- You make do with what you can get! The joy of cars, in my mind at least, is that if you get something slightly imperfect, or not designed for your application, it can be done. You just have to man up!

Why would it not be a reliable source of extra grunt? Would it not give off the same amount of oxygen per mole or it depends on temperature/pressure/whatever?

One a different note, for those who are running nitrous (kenny?), what kinda frequency can those solenoids take before they get really pissed? I mean, a lot of setups I see feel like glorified carburator-era stuff: choose a jet, open the solenoid and go for it (or hope that you got the mixture right). I imagine there are some setups where you can have a much broader -- by pulsing the solenoids for instance -- and real time control of the output.

Seeing as how I actually know someone first-hand who put the spray on an otherwise stock B21F, who actually knows both Volvo stuff and NO2 stuff, I figured I can at least post results.

Stock, high-mileage B21 from an 81 I believe non-turbo. Motor only ran low 17's. Either a 50 or 75 shot (can't remember, it's been a few years) and he dropped to 15.9. Second pass he wiped out the boot. One of the 2 passes spraying he took out the HG as well, when he found a solenoid had accidentally gotten hooked up wrong and he was spraying outa the hole, and for the entire run.

the general rule of thumb is 30%
so whack in 30% shot of juice and it MIGHT take it
its hardly a reliable source of extra grunt. the oxygen is separated from the nitrogen and burnt off while the nitrogen acts as a buffer

great for moistening the chicks man

30%? lol. That would mean, on a b230F, a what, 5hp shot?
We've run as much as 96% and the engine was fine. Hauled serious ass too. its as reliable as the user, kinda like a turbo setup.

Nitrous mastermind, and a couple other things like that. they're not too expensive either, about $400 avg.

Megasquirt 3, WHAT?

why wait on bruce and al? you'll be waiting for a while.

too much timing sounds like it. too much spray down low, maybe.. but usually when that happens you get a really impressive backfire out the intake that wraps the throttle plate around the shaft and/or blows apart the intake.
